Using Variables In Switch Statement Case Clauses

May 19, 2014

I am stuck with two switch statements that I feel I am close to achieving. My first switch statement is to generate random mathematical operators for the math questions in the game (generated randomly) My second switch statement is to determines which action the system will take upon the correct or incorrect answer. For the first switch statement I have a variable called num. Num is a random integer. I have an operator mapped to each outcome of num. In my second switch statement I am trying to use the variable answer as a variable in the first case but do not know how.

package pkgnew;
import java.util.Scanner;
import java.util.Random;
public class New {
public static void main(String args[]) {
//Declare and construct variables

String Value To Be Name Of Variables Created

Mar 11, 2015

Is it possible to have the value of an entered String to be set as the name of the String to be created whilst running.For example: String username= Keyboard.readString() & the user entered for example the word: "Hello".Is there a way how I can make the Java Program create another String named Hello (Inputted value of String username).

If this is allowed, what do I have to use and if possible show me exactly what I have to do with the example mentioned above?

Using String And Boolean In If Statement?

May 24, 2015

I want to write a program that ask if you want to go to the movies. If the user type in yes then it'll print out (Alright let go) but if the user type no then it would print (whatever). The trouble that I'm having is. What's the best way to use Boolean and Strings together in a if statement?

public class Night {
static Scanner UserInput = new Scanner (System.in);
public static void main (String [] args){
boolean user1, user2;
user1 = true;
user2 = false;

Finding String Length Without Variables

Oct 14, 2014

The problem asks me to write an expression whose value is the number of characters in a specific string. Normally, it would be a simple task of using the String.length() method, but that is not allowed. In fact, no variable declaration is allowed (it's a MyProgrammingLab assignment, if any are familiar).

Simply put, if I have a String "This is a sample string." is it possible to find the length without assigning it to anything?

In other words, the code must be able to go into the parentheses of System.out.println( ); and correctly print the length of said string.

The answer, for those curious:

System.out.println("This is a sample string.".length());

I didn't know the .length() method could be called on a literal. Now if only I could find out how to close this thread...

If Statement - Char To String Casting?

Aug 3, 2014

import java.io.IOException;
import java.util.*;
public class Guesser {
public static void main(String[] args) throws IOException {
 char[] alphabet = "abcdefghijklmnopqrstuvwxyz1234567890 .,:;'-".toCharArray();

[Code] .....

I'm writing a program which will take a three letter word (for now) and then try to guess the word over and over again until it finds it, then print the word and the amount of tries it took to find it.

The problem: at the moment the program will find the word but not break out of the for loop when it does. I think it doesn't like the char to String conversion somewhere along the line.

Implement Dynamic String Into SQL Statement

Aug 26, 2014

I have some spatial datasets which are availabe in a opensource metadata catalog software GeoNetwork and in a PostGIS database.The problem is that the student who created the database used different IDs for the same datasets. So the IDs in the GeoNetwork differs from the IDs in the postGIS database. They only have the same name So, if someone uploads a new dataset into GeoNetwork, the same dataset is uploaded into a postGis database too.

Now I want to add a ID column into the database to give the field the same ID like the ID in geonetwork. I think I can only do this with using the filename cause they are same in both cases.Now I want to alter the table in eclipse with following code:

PHP Code:

Connection con = null;
Statement stmt = null;
String query = null;
String filen = filename.substring(0, filename.indexOf('.'));
con = DriverManager.getConnection("jdbc:postgresql_postGIS://localhost:5433" + "user=postgres;password=dominik1;" + "database=geonetwork"); --> (the connection data will later be in a properties file)
query = "ALTER TABLE " + filen + " ADD GN_id INTEGER(10) ";
stmt = con.createStatement();
stmt.execute(query); mh_sh_highlight_all('php');

But i get the following findbug error:

Failed to execute goal org.codehaus.mojo:findbugs-maven-plugin:2.5.2:check (default) on project services: failed with 1 bug
org.fao.geonet.services.resources.UploadAndProcess .exec(Element, ServiceContext) passes a nonconstant String to an execute method on an SQL statement ["org.fao.geonet.services.resources.UploadAndProces s"] At UploadAndProcess.java:[lines 83-299]..

I tried to suppress this error and worked with PreparedStatement and String.Format but I can't get rid of this error.

Randomize Placement Of Variables In Outputted String

public class PasswordGen {
 public static void main (String[] args) {

public static void Generator() {

I'm trying to make a random password generator, but it isn't as random as I'd like it to be. I have set places where either a number, letter or symbol can go. I'd like to randomise the placement of these set types in the output from "symbol + letter + number + letter etc" to "? + ? + ?". Sample output from this code:

Two Dimensional String Array - Accessing Variables

Feb 5, 2015

Suppose I have private static void name() { ... } that has a two dimensional string array named array[. Now suppose I have private static void different() {...} and I want to write a condition where if (item == array) { ... }, how can I access my array from name() when I am in different()? I get a compile error saying cannot find symbol. My code is similar to:

Java Code:

public static void main(String[] args) {

String item = keyboard.nextLine();

Sorting Array Of Objects Based On One Of Class String Variables

Apr 8, 2014

I have a school assignment that involves me sorting an array of objects based on one of the class String variables. I am using as the title says a simple selection sort method. The problem I'm having is that when I run the program in debug mode, it never seems to enter the if statement in the inner loop. I would like to say I've tried a number of things to figure it out, but honestly I'm just stumped as to why it's not working.

Here is the code:

public static void sortTransactions(Transaction[] oTransaction){// This is the sorting method, obviously it's not done so it currently just prints to screen.
System.out.println("Successful call to sortTransaction()");
String min = "";
int curInd = 0;
Transaction[] temp = new Transaction[1];

[Code] ....

The output when I check to see if the array is sorted verifies that the array never does get sorted.

Why Does String Split Method Producing Arrays With Whitespace Variables

Jan 17, 2015

I used the string split method in the following lines of code like this:

String[] numbers = out.split("[^d.]", 0);
String[] operations = out.split("[.d()]", 0);

When out is equal to the String "2x2.5", the array operations ends up looking like this when it is printed using the toString method:

[, , , x]

As you can see, before the array element x, there are three String variables which only contain whitespace. Why does this occur, and how can I prevent this from happening?

How To Turn If Statement Into A Case / Switch Statement

Jun 19, 2014

So from what iv learnt in Java and programming in general is that using a case statement is far more efficient that using multiple IF statements. I have an multiple IF statements contained within a method of my program, and would like to instead use a case statement.

public String checkPasswordStrength(String passw) {
int strengthCount=0;
String strengthWord = "";
String[] partialRegexChecks = { ".*[a-z]+.*", // lower
".*[A-Z]+.*", // upper
".*[d]+.*", // digits
".*[@#$%!]+.*" // symbols

How To Run If Statement

Apr 5, 2014

I'm trying to run an if statement with an input condition and here is my code.

import java.util.Scanner;
public class App10A {
public static void main(String[] args) {
Scanner fun = new Scanner(System.in);
System.out.println("What's your name?");
String name = fun.nextLine();

[code]....

When the computer asked me "What's your name?", I typed in Victor, then the result turned out to be "Oops, try again!".I typed in Victor (without parenthesis) and "Victor" and both gave me the negative results.What exactly should I put in in order to get "This is the result I wanted!" ? how should I modify my code in order to get "This is the result I wanted!" when I put in Victor (without changing the equal sign)?

Comparing Two Variables

Mar 30, 2014

Let's get it out of the way -- I'm stumped. On something that should be pretty simple to solve. Code follows.

public class Sum {
public static void main(String [] args) {
Double nSum = 0.0;
Double aDouble = 100.0;
for (int i = 0; i < 1000; i++){
nSum += 0.1;

[Code] ....

The output:

100.000000
100.000000
false
false
false
false
false

Process finished with exit code 0

I wrote another simple program and hardcoded the values: aDouble = 100.0; bDouble= 100.0000

Using aDouble.equals(bDouble) returns true, just as one would expect.

So what am I overlooking?

How To Use Variable In If Statement

How do I use a variable in an if statement to return a public void method from another class? I've tried:

Scanner myScanner = new Scanner(System.in);
myScanner.nextInt();
if (myScanner.nextInt()==1) {
carSelection colour = new carSelection();
colour.carSelection();

The method colour in class car selection is just 4 print line statements? I've // out the if statement to see if it is correctly calling the method and displaying the data and it is?
